Check this out..some very creative uses of fiber optics, frequency syntyisizers coupled to the primary coils of these two large Tesla coils!!
Note: There are no speakers involved in this video. The sound is being produced by the high voltage generated from the coils as they are triggered by the frequency synthisizer's AC signals being fed to the Tesla coil's primary windings. In effect, the primary winding of each tesla coil acts just like the coil in a regular speaker. Only in this case...the electrical pulses are not causing a coil to move across a magnet to produce variances in the air which produces sound from a speaker, but rather making the secondary winding actually producing high voltage sparks that resonate with the input signal, causing the sparks to "sing".
